Hi,
this change
2008-06-30 Chong Yidong <cyd@stupidchicken.com>
* xfaces.c (Finternal_merge_in_global_face): If default face was
modified, realize it again. Update the font face attribute.
makes Emacs segfault in batch mode.
The culprit is the bcopy(oldface->lface, ...) according to the
stacktrace. I couldn't get gdb to let me inspect oldface (any hints?).
Reverting this change works for me.
Hannes

It's probably optimized out. You should recompile Emacs without
optimization (CFLAGS='-g' ./configure; make) and try again.
Please provide a recipe to reproduce this segfault.

I did that (-O0 -g) and could inspect other stuff in this context, not
this. Weird.

emacs -batch -f format
